What we could not verify
- The US store finder only shows the New York store, so the store locator link is R.M.Williams' Australian one.
- The help link goes to the FAQ page; the separate help centre address did not open.
- No sale or outlet section, loyalty programme or shopping app was found.
Questions
Which length does R.M.Williams's size chart list?
R.M.Williams's charts give these lengths — CM: length scale not clear. A measured foot length and a size in cm are about 8 mm apart for the same size, so compare your own foot length only with a column on the same scale.
Does the official chart tell me how a R.M.Williams shoe will fit?
Only in part. The chart gives the length each size is meant for; how a particular model fits also depends on its last, width and materials, which the chart does not show. R.M.Williams's size guide does not give general advice on sizing up or down; fit also varies by model and foot shape.
When should I not compare R.M.Williams sizes with another brand?
When the two charts list different lengths. A measured foot length and a size in cm are about 8 mm apart, and the length of a foot is not the inside length of a shoe, so such a match can be half a size or more off. The converter matches only lengths on the same scale and lists the other brands separately. R.M.Williams's chart has no length on a clear scale, so it is not matched with other brands at all; use its own chart and advice.
When was R.M.Williams's chart last checked?
On 2026-10-31, against R.M.Williams's official size guide linked under each chart. The date changes only when the chart is checked again against the official page or its numbers change, not when this page's layout or wording changes.
